Anti-MASP1 Antibody

Offered through the Antibodies.com catalogue as a primary antibody for complement and immunology research, this affinity-purified reagent is raised in rabbit against mannan-binding lectin serine protease 1 (MASP1) and is supplied as an unconjugated polyclonal antiserum. The reagent is provided at a working concentration of 1 mg/mL in a 50 µL volume, formulated in phosphate buffered saline (PBS) at approximately pH 7.2 with 15 mM sodium azide as preservative, and it is validated for Western blot (WB) applications. Endogenous levels of total MASP1 protein can be detected in samples originating from human, mouse and rat, making the antibody suitable for cross-species investigations of the lectin complement pathway. The host species is rabbit and the clonality is polyclonal, while the conjugate status is unconjugated, allowing users flexibility in downstream labelling strategies such as HRP, biotin or fluorophore coupling. For storage, the antibody should be kept refrigerated at 2–8 °C for short-term use; for longer-term storage, aliquoting and freezing at -20 °C is recommended, with repeated freeze/thaw cycles avoided to preserve activity. Produced under the Antibodies.com quality standards and listed within the supplier's primary antibody portfolio, this rabbit polyclonal anti-MASP1 reagent is intended for research use only and is appropriate for laboratories studying complement activation, innate immunity and serine protease biology.
